Prefabricated House Collapse Video

The following videos are related to the collapse of prefabricated houses:

Collapse of the Wulong Canteen: In this incident, a canteen in the Wulong area collapsed. According to residents, the canteen building was an old brick-and-mortar prefabricated house. The prefabricated structure may collapse due to aging, loosening, or insufficient load-bearing capacity at the connection points when subjected to long-term use or external forces. This accident highlights the potential risks in the maintenance and safety of old prefabricated houses.

House Collapse in Wanyuan, Sichuan: Heavy rainfall in the Wanyuan area of Sichuan triggered geological disasters, causing multiple civilian houses to collapse instantly. Among them, some collapsed houses adopted a prefabricated structure. Under the influence of geological disasters such as mudslides and landslides, the stability of prefabricated houses is severely challenged, especially when the house foundation is damaged, the connections between prefabricated panels may fail, leading to the collapse of the entire structure.

Collapse of an Old Building in Shijiazhuang: An old building in Shijiazhuang collapsed in the early morning, resulting in three deaths. Reports indicate that the building was a prefabricated house. Old prefabricated houses generally suffer from material aging, structural degradation, and other issues due to their long construction age. Coupled with possible illegal renovations and overloading, the safety of these houses is significantly reduced, making them highly prone to collapse accidents.

Earthquake Collapse Case in Venezuela: During a strong earthquake in Venezuela, a large number of prefabricated houses built in the 1950s and 1960s experienced vertical compression collapses. Video footage shows the collapse process of typical prefabricated structure buildings under earthquake action. The reason why prefabricated houses are vulnerable to damage in earthquakes is that their overall structural integrity is poor, and the node connections are weak, making it difficult to effectively resist the horizontal and vertical forces generated by the earthquake, leading to structural damage and collapse.
